A racehorse is not an expendable commodity, but an athlete. They are started far too early in their lives--against their will--before they are physically mature enough (4 years min) to handle the heavy demands of racing and this so why they break down after such short careers. So, they are bred in excess, (quantity over quality) used up fast, and sold to slaughter when they're broken. How about a law extending the age requirement for a horse's first start? Penalties for abuse? Of course not. That would be logical and humane. Let's just reward the abusers with an easy out when they indulge in a fantasy, overtrain a horse, or make a bad investment. When they destroy thousands of horses each year. F- that. If an owner is careless with this investment, too bad. They don't get a tax break. Let them eat it and learn to be better at their jobs.
